SHADE-ROLLER.

SPECIFICATION forming part of Letters Patent No. 640,604, dated January2, 1900.

Application filed October 5, 1899.

T aZZ whom it may concern: I

Be it known that I, ARNE S. TRAGETHON, a citizen of the United States,residing at Kensett, in the county of Worth and State of Iowa, haveinvented certain new and useful Improvements in Shade-Rollers; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in adjustable shade-rollers; andthe object is to simplify and improve the construction and increase theefficiency whereby the roller may be adjusted to suit any window.

To these ends the invention consists in the construction, combination,and arrangement of the several elements of the device, as will behereinafter more fully described, and particularly pointed out in theclaim.

In the accompanying drawings, the same reference characters indicate thesame parts of the invention.

Figure 1 is a perspective view of my shaderoller as it appears inposition. Fig. 2 is a longitudinal section of the same. Fig. 3 is adetail view of the winding end of the roller. Fig. 4 is a similar viewof the opposite end. Fig. 5 is a transverse section on the line a; w ofFig. 2. Fig. 6 is a similar view taken on the line y y of Fig. 2. Fig. 7is a perspective view of the brackets which support the roller inposition.

1 denotes the solid end of the roller, which is provided with a flange 2and a cylindrical journal 3,which has a bearing in the bracket 4.

5 denotes a band which has its lapped ends secured to the solid end ofthe roller contiguous to the flange 2 by the screw 6, and the end of theshade 7 is also secured between the lapped ends of said band by saidscrew 6. The opposite end of the solid roller 1 is adj ustably securedin the tube 8 by means of the screw 9, which passes through the ear 10of the tube and the shade 7. This tube 8 is provided with a longitudinalslot 12, which forms a guide for the edge of the shade, and it is alsoformed with the ears 10 and OZwhich also overlap the shade and aresecured in place by screws 9' and 9 the screw 9 entering a cylindricalblock 13 and the screw 9 being adjustably secured in a sleeve 14, theoppo- Serial No. 732,651. (No model.)

site'end of which is secured in a tube 15 by the screw 9 which passesthrough the lapped ear 10 and shade, as in the prior instances, and theouter end of said tube 15 is formed with a spring-clip 16 to receive theouter end of the shade, as shown. This end of the tube 15 forms abearing for the collar 17, which is integral with the flange 18, thelatter being provided with a rectangular orifice 19 to receive thecorrespondingly-formed shank 20 of the bracket 20.

21 denotes a hub fixed in the collar 17 to receive the fixed end of thewinding-shaft 22, which extends through the sleeve 14, its outer endterminating in a duplex ratchet 23, projecting into the path of thepawls 24 25, piv oted on the contiguous end of the sleeve.

26 denotes the winding spring encompassing the shaft 22, one end of thespring being fixed to the sleeve 14 and the other end to the stationaryhub 21.

When the shade is drawn down, the tubes 15 and 8, the sleeve 14, and theroller 1 all rotate to wind up the spring and the shade held in positionby either of the pawls 24 or 25, engaging the ratchet 23, whereas toraise the shade it is first drawn down a short distance and allowed torewind rapidly, so that the pawls will be thrown outward by centrifugalforce and pass the ratchet, and when the proper point has been reachedthe shade is stopped for a moment and'then allowed to move upwardmoreslowly to give the pawls time to drop by gravity into the ratchetand thereby lock the roller at the desired point.

As before stated, it will be understood that the solid roller 1 islongitudinally adjustable in the tube 8 by means of the screw 9, and theopposite end of said tube is correspondingly adjustable on the sleeve 14by means of the screw 9 thus permitting the roller proper to belengthened or shortened at will to correspond to the width of the shadeand windowframe to which it is to be adjusted.

The accompanying drawings show my invention in the best form now knownto me; but many changes in the details might be made within the skill ofa good mechanic Without departing from the spirit of my invention as setforth in the claim at the end of this specification.

Having thus fully described my invention,

10 winding shaft and spring, and the ratchet fixed on said shaft in thepath of said pawls, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
